Arrowmax 64P 40T 7075 Hard Pinion Gear - AM-364040

The Arrowmax AM-364040 is a 64 pitch 40 tooth pinion gear machined from 7075 aluminium for use in competitive RC car drivetrains. Designed for 1/10 and 1/12 scale electric RC cars running a 64P gear pitch, this pinion gear is a direct-fit component for touring cars, pan cars, and similar competition-class builds. The 7075 aluminium alloy construction makes it significantly harder and more wear-resistant than standard 6061 aluminium, which is why it's a popular choice among racers who want consistent mesh and longer service life from their drivetrain components.

Key Features

• Machined from 7075 hard aluminium alloy for improved hardness and wear resistance over standard aluminium pinions
• 64 pitch (64P) tooth profile — must be paired with a 64P spur gear for correct mesh
• 40 tooth count suits higher top-speed gear ratios depending on motor kV and spur gear size
• Precision CNC machining ensures consistent tooth profile for smooth, low-noise gear engagement
• Lightweight aluminium construction reduces rotational mass compared to steel pinion gears

Compatible With

• 64P (64 pitch) gear systems on 1/10 scale electric touring cars
• 64P gear systems on 1/12 scale pan cars and competition RC cars
• Arrowmax and other brands' 64P spur gears
• Motor shafts requiring a 40 tooth 64P pinion — confirm bore size before fitting
